It's no secret that Hollywood is full of talented actors and actresses that never fail to entertain us. Some of these actors have been around for decades, others have gained international recognition fairly recently.

Some of these actors are very similar to their fellow actors either in terms of their appearance (there are countless of actor lookalikes in Hollywood) or in terms of their acting style. Others are completely unique and irreplaceable. Still, with so many talented actors around - and with many more waiting for their breakthrough - it must be incredibly difficult for film directors and casting teams to choose the best actor for any particular role. In most cases, Hollywood movie casting decisions are perfect. In other, much rarer, cases they are not.

Still, while it is certainly hard for directors and casting teams to choose between actors, it is no less difficult for us - the viewers - to choose between our favorite actors and actresses too. Nonetheless, that is exactly what we want fans to do here today. We are asking everyone to pick which actors are their favorites from the ones we've listed in this quiz. The reward? We'll guess everyone's sign!
